.. include:: /../getting_started/vars.rst .. _section-Product-SecureWan-610: RTI Secure WAN Transport ************************ .. note:: RTI may not support *Secure WAN Transport* in future versions of |CONNEXT|. Existing applications that use it should be updated to take advantage of *RTI Real-Time WAN Transport* as soon as feasible. All new applications should use *RTI Real-Time WAN Transport*. See: :link_rwt_usersman:`Real-Time WAN Transport, in the RTI Connext DDS Core Libraries User's Manual <>`. OpenSSL upgrade =============== Release 6.1.0 of *Secure WAN Transport* uses OpenSSLĀ® 1.1.1k. (Release 6.0.0 used OpenSSL 1.0.2o, and Release 6.0.1 used 1.1.1d.) *Secure WAN Transport* 6.1.0 is API-compatible with OpenSSL versions 1.1.1 through 1.1.1k, but not with OpenSSL 1.1.0l or below. If you need *Secure WAN Transport* 6.1.0 to run against older versions of OpenSSL, please contact support@rti.com. For instructions on installing the latest version of OpenSSL, see the :link_wan_install_guide_610:`RTI Secure WAN Installation Guide 6.1.0 <>`. .. BUILD-2667 Changed OpenSSL static library names ==================================== The OpenSSL static library names no longer have a "z" suffix. Therefore, when including the static libraries in a makefile, we recommend including the whole path to the OpenSSL static libraries in order to avoid confusion with the dynamic libraries. See: :numref:`section-OpenSSL-Namechange` for details. .. BUILD-2848
